- A karst landscape developed on, or perhaps above, gypsum or similar evaporite rock sequences. Dissolution of gypsum by ground water in buried, interstratal, situations is common and the effects of such dissolution may be expressed at the land surface in the form of subsidence depressions. There are extensive areas of gypsum karst in North America and the Ukraine but British examples are limited to rare caves, exposed by quarrying, and subsidence depressions above dissolved gypsum beds, such as those around Ripon, Yorkshire .
